Specification of Letters Patent.

Patented July 9, 1907.

Application filed. December 18, 1905. serial No. 292,299.

To all whom it may concern:

Be it known that I, OTTO VON TREsKow, captain of horse, a subject of theGerman Emperor, anda resident of 7, Sembritzkistn. in Fiirstenwalde, asmall place on the Spree, inthe Province of Brandenburg, in the Kingdomof Prussia, German Empire, have invented certain new and usefulImprovements in Back-Supports, of which the following is aspecification.

1 The present invention relates to a baclosupporting device for use onwalks, on excursions; in mountaineering and the like.

The device is adapted to be placed on a walking stick or alpine stockand to be held by a stronger person against the back of a Weaker person,walking in front of the latter, especially during the mounting of steepascents, in climbing etc, whereby the weaker person is assisted in aneffective manner.

One embodiment of the object of the present invention is illustrated inthe accompanying drawings, in

which:

Figure 1 is a plan view, Fig. 2 a longitudinal section through thedevice with a stick attached to it.

In the form of construction drawn, theobject oi the invention consistsof the plate a which is advantageously arched or curved to correspond tothe horizontal profile of the back of the person to be supported, andthe supporting surface of which, in order to prevent it from slipping,is provided with flutings, corrugations or the like, or is roughened,Whereas on the other side oi the plate a a socket is provided forreceiving the point or end of a stick or alpine stock. This socket inthe form of construction is comprised of a suitable number of springtongues 1) formed integral with a ballc. This fits in a cup d suitablysecured to the plate a, so that tllCSOCkOt b is connected with the platea by a ball-andsocket joint, and it will be seen that a stick (2 (shownin dotted lines) being inserted in the socket I), the person supportinganother may in each case move the stick in such direction as is requiredto assist the person in the most appropriate manner.

As a special advantage of this invention, it may be mentioned that thenew back-support can be carried in the most convenient manner in thepocket without occupying any space worth mentioning.

I am aware that it has previously been proposed to use plates, fittedwith operating arms, [or the purpose specified, and I donot claim suchinvention; 1 Wish however to be understood that in no respects is myinvention restricted in scope to the particular form of constructionillustrated and described, but that the scope'is indicated by theappended claims.

What I claim is:

A back support, consisting of the combination of a plate adapted toreceive the hack of a person, a cup (I secured to such plate, a ball 0fitting in this cup and having spring tongues 1) adapted to hold the endof a stick, as described.

In witness whereof I have hereunto signed my name this 5th day ofOctober, 1905, in the presence of two subscribini witnesses.
